I never quite appreciated the scale of Indonesia. Its length is about the same as Boston to London. And ~21% longer than Seattle to Miami.

New paper led by @CUBoulder PhD student Max Elling shows that tropical oceans drive year-to-year malaria variability in Malawi. Soil moisture is the key link and a foundation for early warning systems. nature.com/articles/s43856-0… @CIRESnews @CUBoulderATOC

Tropical oceans drive variability in soil moisture and malaria in Malawi

Let's talk about Luis Rojas, the @Yankees third base coach. How do you make this send? Yes Bellinger is fast, and no Duran's arm is not the strongest in the league, but a throw from shallow left and 90 feet to go? This was decision opened up the game. Please help, @Jomboy_

"my mentee sent an email thanking me for my support and guidance, which she said helped increase her confidence. She probably doesn’t know that she helped increase my confidence, too." science.org/content/article/…

As a Ph.D. student, I felt unprepared to mentor—but I’m glad I took the leap

“I could help even when I did not have a solution,” this scientist learned
